Be it.. known that I, ALExr-Faau., a subject of the Czar of vRussia residing-at Los Angeles,y in the count of lios Angelesy and State of California, veinvented certain new and useful Improvements in Aeroplanes, of which the following is a specification.

This invent-iolnrelates to aeroplanes and lhas for one of its objects to provide an auxiliary supporting body which may be thrown into an operative position when the laeroplane cannot be controlled. lWith this device, many accidents will be prevented and make air n'avigation a more desirable sport. 4

A further object ofthepresent invention resides in constructing the forward edge of each plane with a rearwardly and downwardly extendingsupporting surface, the

same tending to cause the body to r'ise upwardly and ride more smoothly.-

For a full understanding of the present invention reference is to be had to the following description and to the accompanying drawings, wherein- Figiirel is a perspective view vof an air- ,ship embodying the present invention. Fig.

2 is a front elevation the-reo'. Fig. 3 is a side elevation of the invention.- Fig. 4.- is a fragmentary sectional view illustrating the manner in which the auxiliary ing body is normally carried.

Throughout the following det-'ail description and on the several figures of the drawin s, similar parts are referred tov by like re erence characters.

As illustrated, the invention is applied to a bi-plane type of air-ship l, although the same may be embodied in othertypes without departing from the scope of the present invention. The bi-plane consists of the superposed supporting'planes 2 and 2 having the forward rudder 3 spaced therefrom and a rear rudder 4 mounted-in advance of the vertical rudders 5. Any suitable ropelling mechanism 6 may be employed.

The upper plane 2 is provided with 'a central opening 7 which opens into a casing 8 interposed between the planes, =said` casing being of any desired shape but preferably cylindrical, as illustrated. Secured in the bottom of the casing 8 is a fiexible cable 9 carrying on its free terminal an auxiliary supporting body l0 of the parasupportparachute 10.

position 1s faded and-.loosely paced inthe casing 8 and isretained thereinbyja cap, 11 fitting overthe opening 7. j v The top-or cap 11. is secured to the para-j hute4 10 by. any suitable connectionl2 "and also has secured thereto a latch -13 which, u:

is engaged bya plurality of. spring.actuatedu catches 14 to` securellock the capfclfo'se down onto the .aerop ane 2. .These `spring actuated catches 14 are retracted "by any suit-able means such as a 'flexible connection 15 Whichmay terminate -within reach of the aviator. When it is desired to project the auxlliary supporting body 10 tojanoperative position; the flexible cords 15 are pulled -to `retract the catches 14, whereby the top or czzip 11 is free to move from the open'- 1n of the4 casing 8 are a plurality of spring actuated plunger-s or projecting members 16 which are adapted to bear against the latch 'member 13, and when the -catches 14 are retracted, said cap 11 upwa 1y, Vwhich will be acted upon by the air and draw`thel parachute out of the casing into an operative position, as illustrated in Fig. 1. f

.The -cord 9 is secured to the top plane by a plurality of cords 17 so that the body of the machine will be evenly supported by the 11 may he-made of any desirable material projecting membersv force theounted on the side of. the upper portion and since the same lines flat on the plane. it-

affords no resistance i-n the forward movevment of the part.

' The forward edge of each aeroplane is provided with an auxiliary tip 18 having a sharp cutting edge and a downwardly and rearwardly extending sustaining surface 19 which reduces the tendency of the aeroplane to dip.

It will be observed from Fig.` 2 that the terminals of the bottom pla-ne 2 are deflected upwardly and contact with Vthe top plane 2 so that, should any wind strike the machine on the side, the tendency will be to raise said machine while any lateral tipping may be overcome by manipulating the several rudders and pi'opellers, as desired. y V

The rear portion of the machine is provided with a yieldingly mounted skid or shoe 20, as is clearly illustrated in Fig. 3. x

Of course, it will be obvious that the rudders may be manipulated by the cords 'orV g A, p 1,087,749

In a machinepfor aerial navigation, an aeroplane, a casing, an auxiliary supporting body mounted in said casing, a closure for said casing adapted to form a portion of Vthe aeroplane aforesaid when said closure is ...in an operative position, spring actuated means to retain the closure 1n an operativev position, spring means disposed on the side of the casing for vmoving the closure to an inoperative position and said auxiliary supporting body to an operative position, and means for releasing said closure.

In testimony whereof I afiiX my signature in presence of two witnesses.
